To serve a function to be described, each `of the plates-48 is provided with an arcuate slot 52 which extends inwardly from itsupper edge and is positioned adjacent the other end thereof.

Reference numeral S4 connotes, in general, a substan tially U-shapedhinge bracket which includes a bight portion 56 from the longitudinallyextending marginal edges of which depend a pair of laterally spaced andsubstantially parallel side arms 58, 60 which terminate atv theirrespective outer ends in diverging ilanges 62, 64. As is best seen inFigures 6 and 8, the bight portion 56 is angularly inclined with respectto the ilanges 62, 64.

A hinge bracket 54 is secured to each of the hinge plates 48 with theanges 62, 64 being juxtaposed thereagainst intermediate the ends thereofand being rigidly secured thereto as by welding. As is seen in Figures land 2, the ilanges 62, 64 extend transversely across their respectiveassociated hinge plates 48. A hinge leg for each of the hingebrackets 54is generally indicated at 66 and is seen to comprise an elongatedsubstantially hollow cylindrical member 68 having a closure Wall 78extending across one end thereof and from which projects a tongue 72extending diametrically thereacross. Each of the tongues 72 are receivedwithin one of the hinge brackets 54, respectively, and are pivotallyconnected on the side walls S8, 60 on pivot pins 74.

Reference numerals 76 denote a pair of identical standards or legs whichhave an elongated substantially hollow cylindrical conguration. rl`heupper ends of the standards 76 are telescoped within the cylindrical member 68 and are retained therein by lock pins 78. One of the standards 76is provided with a radially projecting headed stud 80 adjacent the upperend thereof, and a similar headed stud 82 projects radially from theother of the standards 76 adjacent its lower end. To the former ispivotally secured at 84 one end of an elongated substantiallyrectangular lever 86 having a slot 8S adjacent one end thereof and asecond slot 90 spaced inwardly from the slot 88. As is seen in Figure 1,With the standards 76 disposed in their operative position, the lever 86is pivoted to extend thereacross with the stud 82 engaged within theslot 88, the lever 86 in this case Iacting as a cross brace to preventmovement of the standards 76 relative to each other. When the standards76 are moved to their inoperative position, as shown in Figure 2, thelevers 86 are pivoted thereagainst and extend longitudinally thereofWith the stud 80 being received Within the slot f90 and thereby limitingthe pivotal movement of the levers 86 in one direction.

Intermediate the ends of the side walls 14, 16 are secured outwardlyopening vconvoluted resilient support clips 92 each of which include abight portion 94 from the ends of which project a pair of curvilineararms 96, 98, the outer end of the latter being integrally connected withthe outer end of a third curvilinear arm 100, connected by a bight 102to a fourth curvilinear arm 104. The bights 94, 182 of each of the clips92 are welded to the side walls 14, 16.

The other ends of the side Walls 14, 16 are each slotted at 106 and cutout at 108 to serve a function to be described. The bottom wall 20,adjacent the other end of the outer member 12 is provided with a stopclamp 118. The stop clamp 110 comprises an elongated substantiallyU-shaped channel member having a centrally positioned bight portion 112(see Figures 4 and 5) from which project a pair of laterally spaced andsubstantially parallel side arms 1114, 116 which terminate in outwardlydiverging flanges 118, 128 that extend longitudinally or' the bottomwall 20 on each side of the slot 22 and are secured thereto as bywelding. The bight portion -112 terminates .at y.one of `its ends in `aclownwardly curved cam element 122 and at its other end in an upwardlycurved abutment 124.

The barricade 18 also includes a central, elongated, substantiallyhollow rectangular section 126 having a pair of opposed confronting openends, a pair of longitudinally extending, substantially rectangular,laterally spaced and parallel side walls 128, 138, and a pair oflongitudinally extending substantially rectangular, laterally spaced andy parallel top and bottom walls 132, 134. An elongated,

substantially rectangular slot 136 extends transversely through thebottom wall 134 throughout its length, the slot being centrally spacedintermediate the side walls 128, (see Figure 7). The bottom wall 134,adjacent each end thereof, is provided with downwardly or outwardlyexpressed offset ends 138, 140.

Reference numeral 142 denotes an elongated substantially T-shaped clampbar having a stem 144 (see Figures 4 and 6) and a crosshead 146. Thecrosshead 146 is i'ixedly secured to the oiset bottom Wall portion 138with the stem thereof projecting downwardly through the slots 136 and22, in that order, to serve a function to be described.

The side walls 128, 139 adjacent that end of the central section 126carrying the clamp bar 142 is formed with an inwardly extendingelongated slot 148 aligned with and having a width slightly greater thanthe outside diameter of the spacer member 38 and a cutout portion 150having a width slightly greater than the outside diameter of the spacermember 44. The other end of the side walls 12S, 130 are provided withelongated slots 152 and cutouts 154, and the expressed portion of thebottom wall 136 has secured thereto the crosshead 156 of an invertedsubstantially T-shaped clamp bar 158 having a longitudinally extendingstem 160 projecting inwardly within the central section 126.

The inner section of the barricade 18 is designated at 162 and is seento include an elongated, substantially hollow rectangular member havinga pair of opposed confronting open ends, a pair of longitudinallyextending substantially rectangular, laterally spaced and parallel sidewalls 164, 166, and a pair of longitudinally extending substantiallyrectangular, laterally spaced and parallel top and bottom walls 168,170. An elongated, substantially rectangular slot 172 extendstransversely through the bottom wall throughout its length, the slot 22being centrally spaced intermediate the side walls 164, 166 (see Figure7). The bottom wall 170, adjacent the outer end of the inner member 162is provided with a stop clamp 174 similar to the stop clamp 110, butinverted with respect thereto. The stop clamp 174 comprises an elongatedsubstantially U-shaped channel member having a centrally positionedbight portion 176 from which projects a pair of laterally spaced andsubstantially parallel side arms 178, 180. The side arms 178, 180 aresecured to the adjacent sides of the side walls 164, 166 by conventionalmeans such as, for example, welding. The bight portion 176 at its outerend terminates in a downwardly curved abutment 182, and the other endthereof terminates in an upwardly curved cam element 184.

The other end of the inner section 162 of the barricade 10 is providedwith an inner tie member 186, the tie comprising an elongatedsubstantially U-shaped channel member having a bight 188 from thelongitudinally extending marginal edges of which project a pair oflaterally spaced and substantially parallel side arms 190, 192, thelatter being lixedly secured to the adjacent inner sides of the sidewalls 164, 166.

To serve a function to be described, the inner ends of the side walls164, 166 are provided with elongated slots 194 and cutouts 196, theslots 194 being in longitudinal alignment with the slots 48 formed inthe side walls 128, 130, and the cutouts 196 being aligned with thecutouts 150 formed in the side walls 128, 130 of the central section126.

A cylindrical hinge pin 200 extends between the side walls 164, 166 andits opposed ends project beyond the remote sides thereof at pointsspaced inwardly from the outer end of the inner section 162 and belowthe longitudinal axis of each one thereof. A substantially hollowcylindrical spacer member 202 is telescoped over the hinge pin 200 andextends between the adjacent sides of the side walls 164, 166, thespacer member being pivotally secured to the hinge pin 200 by means of acotter pin 204. Between the outer ends of the inner sections 162 and thehinge pin 200 and vertically spaced thereabove is a lock pin 206 whichextends between the side walls 164, 166 and projects beyond the remotesides thereof. A substantially hollow cylindrical spacer member 208 istelescoped over the lock pin 206 and extends between the adjacent sidesof the side walls 164,166 and is connected to the lock pin 206 by meansof a cotter pin 210.

One end of a pair of hinge plates 212 is pivotally connected,respectively, on the outer ends of the hinge pin 200 and is held againstdisplacement by means of the lock nuts 214. The other ends of the hingeplates 212 are each provided with an arcuate slot 216, the function ofwhich will be set forth below.

Reference numeral 218 connotes, in general, a substantially U-shapedhinge bracket which includes a bight portion 220 from the longitudinallyextending marginal edges of which extend a pair of laterally spaced andsubstantially parallel side arms 222, 224 which terminate at theirrespective outer ends in diverging flanges 226, 228, respectively. As isbest seen in Figure 7, the bight portion 220 is angularly inclined withrespect to the anges 226, 228.

A hinge bracket 218 is secured to each of the hinge plates 212 with theflanges 226, 228 being juxtaposed thereagainst intermediate the endsthereof and being rigidly secured thereto as by welding. As seen inFigures 4 and 7, the flanges 226, 228 extend transversely across theirrespective associated hinge plates 212.

A hinge leg for each of the hinge brackets 218 is generally indicated at230 and is seen to comprise an elongated substantially hollowcylindrical member 232 having a closure wall 234 extending across oneend thereof and from which projects a tongue 236 extending substantiallydiametrically thereacross. Each of the tongues 236 is received withinone of the hinge brackets 218, respectively, and is pivotally connectedon the side walls 222, 224 on pivot pins 238.

Reference numerals 240 denote a pair of identical standards or legswhich have an elongated substantially hollow cylindrical configuration.The upper ends of the standards 240 are telescoped within thecylindrical members 230 and are retained therein by lock pins 242.

One of the standards 240 is provided with a radially projecting headedstud 243 adjacent the upper end thereof, and a similar headed stud 244projects radially from the other of the standards 240 adjacent its lowerend.

To the former is pivotally secured one end of an elongated substantiallyrectangular lever 246 having the same configuration as the lever 86previously described. The lever 246 has formed therein adjacent theother end thereof a slot (not shown) to receive the stud 244 in order tohold the standards 240 against movement relative to each other.

Having described and illustrated one embodiment of this invention indetail, its operation is deemed to be manifest. However, a briefdescription thereof is set forth below.

Let it be assumed that the barricade is in its extended position as isillustrated in Figure l, the operator pushes the inner section 162inwardly towards the central section 126 causing stop clamp 174 tobecome disengaged from the clamp bar 160, and as this movement takesplace the outer ends of the lock pin 206 enters the cutouts 154 and theouter ends of the hinge pin 200 enter the slots 152 thereby limiting theextent of the inner section 162 into the central section 126. At thispoint, the slots 148, 194 and cutouts '150, 196 are juxtaposed inside-by-side relation.

The inner section 162 and the central section 126 are then pushed intothe outer section 12 causing the clamp oar 142 to disengage the stopclamp 110. As this movement is continued, the outer ends of the lock pin206 is received within the cutouts 108 and the outer ends of the hingepin 200 enter the slots 106. Substantially simultaneously therewith, thejuxtaposed slots 148, 194 and cutouts 150, 196 receive the outer ends ofthe hinge pin 36 and lock pin 42, respectively. Thus, the barricade 10is collapsed with the component elements thereof assuming theirrespective positions as is illustrated in Figure 2. The levers 86 and246 are now disengaged from the studs 82 and 244 and are pivoted toaxial extension with respect to the standards 76 and 240 on which theyare pivotally connected with the stud being received within the slot 90of the lever 86 and the stud 243 being received within a similar slot(not shown) in the lever 246. The standards 76 and 240 are now pivotedinwardly towards each other on each side of the barricade 10 forreception within the brackets 92 as illustrated in Figure 2.

To effect extension of the barricade the above procedural steps arecarried out, substantially, in reverse. That is, the standards 76 and240 are released from the brackets 92 and pivoted in the oppositedirection in such a manner as to cause the opposite ends of the lockpins 42, 206 to enter the recesses 52, 216 formed in the hinge plates 48and 212, respectively. With the standards 76, 240 so extended, thelevers 86, 246 are pivoted to their operative position as shown inFigure 1, the levers receiving the studs 82 and 244, respectively.

The inner section 162 is now drawn outwardly of the central section 126to effect re-engagement of the stop clamp 176 with the clamp bar 142.Relative movement between the inner section 162 and the outer section126 ceases upon engagement of the downwardly curved portion 182 of thestop clamp 174 with the inner end of the clamp bar 142. Continuedmovement of the inner section 162 causes the central section 126 toslideoutwardly of the outer section 12. The relative movement between theouter section 12 and the central section 126 is limited upon there-engagement of the outer end of the clamp bar 142 with the upwardlyturned end portion 124 of the stop clamp 110. The component elements ofthe barricade 10 have now assumed their respective positions as isillustrated in Figures 1 and 4.
